Hi All,

Over the last couple of months, their have been threads about running their AJ in the car. Some
people have been satisfied with the sound and other have not been.

I bought my iRock about three months ago and have mainly been dis-satisfied with the sound. Their
would be times when it sounded okay, other times their would be radio noise that would drive me
crazy. Since I only use the iRock on long road trips in rental cars, I just assumed that the
problems where related to the location I was in at the time. Unfortunately I spend a lot of time on
the road sometimes driving 10 hours with breaks only for gas.

About a week ago I was testing my iRock before I started another trip and it sounded awful. I put in
some new batteries, and it sounded good. Then I said to myself could that be the problem is the
drifting and sound quality susceptible to the batteries I was using.

I went to Radio Shack and bought their Lighter Socket 3VDC Power Adapter rated at up to 1000mA
(part number 273-1855). I wired it into my iRock. The sound quality was immediately apparent. I can
say after driving to Las Vegas and back that their was no drift or radio noise.

I did have to lower the volume to 75% and the bass and treble to 0dbs. The sound is just great. I
have been using a cassette adapter in my truck, and I have to tell you the comparison in sound
between the iRock and the cassette adapter is like night and day.

The only thing that you have to be careful of when you wire the adapter in is that the wire with the
white stripe on it is the negative. If you wire it to the positive, it either doesn't work or can
burn out your iRock.

Hi Stephen, The process is pretty simple; 1. Remove battery cover 2. Remove the three screws that hold the iRock case together 3. De-solder the read and black

Hi Stephen,

The process is pretty simple;

1. Remove battery cover
2. Remove the three screws that hold the iRock case together
3. De-solder the read and black leads that go to the battery compartment
4. Tin the wires on the power supply.
5. Solder the power supply to the two points on the pc-board where the battery leads had been.
6. Re-assemble the case and you're done.

The hardest part of the process was the actual soldering. THe two places where you need to solder are small and very close together. My
hands are not as steady as they use to be, but I was able to do it with a fine point soldering iron and de-soldering bulb.

One of the nice things about the way that the iRock is designed is that there is a place through the battery compartment door where you
can run the wire through. Looking at the final product, it looks like it came out of the factory that way.

> yes thank you. i was not all that excited about the sound quality of the iroc. is the task of connecting the two a simple project?

has anyone tried upping the voltage on the irock? I m guessing it s either going to burn out or sound fantastic.

Yes, search the archives of this group at around 6 month ago or so. Someone adapted a DC power adapter to one and I believe he ended up increasing the voltage

Yes, search the archives of this group at around 6
month ago or so. Someone adapted a DC power adapter
to one and I believe he ended up increasing the
voltage a little bit to as well. He posted some
pictures of this as well. I can't remember what, if
any the voltage increase was (to 4.5 volts maybe?).
Anyway, he said that it did in fact sound great.

... You can also install a phono plug in the iRock so that it can run off of batteries or AC. http://www.vfaq.com/iRock/ -- Tom Stangl ***http://www.vfaq.com/

I concur, wiring the adapter is much easier, but a bit expensive. Radioshack has the 3vdc adapter for $14 so I decided against it. Then, as luck would have it,

Then, as luck would have it, I had an old adapter for a cd player
sitting in a box - 4.5V instead of 3V. Since I've come to loath my
irock (and because I recently ordered that other device mentioned in
an earlier post), I decided what the hell - maybe it'd boost the
power.

I can't say if it's stronger than your 3v version, but MAN DOES IT
ROCK NOW! I loves it! Loud, loud, loud. I had it playing all day
from noon till about 7pm - kept monitoring the irock for warmth and
it seems fine. So far so good... I'm going on a major roadtrip
next weekend (assuming the hurricane doesn't dampen things) and I'll
let you know if extended use is still fine...
